FARM-GATE.

Specification of Letters Patent.

Patented Oct. 28, 1913.

Application filed December 16, 1912. Serial No. 736,944.

To all whom it may concern Be it known that 1, MICHAEL DILORENZO,

a citizen of the United States, residing at lrondale, in the county ofJefferson and State of Washington, have invented certain new and usefulImprovements in Farm- Gates, of which the following is a specification.

This invention relates to that class of gates which may be opened orclosed by passengers in carriages without descending from their vehicle.

The object of my invention is the provision of improved devices of theclass described of simple construction for actuating a gate.

The invention consists in the novel construction of gate actuatingmechanism and in the adaptation and combination therewith of unlatchingdevices, as will be fully described in the following specification,illustrated in the accompanying drawings, and finally set forth in theappended claims.

In said drawings, Figure 1 is a View in side elevation of a gate andgate actuating apparatus embodying my invention. Fig. 2 is a plan viewof the gate actuating mechanism. Fig. 3 is a vertical sectional viewthrough 3-3 of Fig. 2. Fig. 4 is a detached perspective view of a detailof the invention. Fig. 5 is detached plan view of the looking bolt, oneof the elements of the invention.

lleforring to said drawings, and particularly to Fig. 1, the referencenumeral 1 indicates the main gate post of a gate-way, and 2 a swinginggate ofsuitable construction operatively connected thereto by brackets 3and 4:. The vertical end bar 5 of the gate is provided with a pivotalpin 6 at its lower end mounted in a bracket 4 and at its opposite upperend arranged with a rigidly secured pyramidal metal cap 7 preferablyfitting over the fashioned upper extremity of said bar. At its apex saidcap is formed with a circular bearing 8 pivotally engaged in a collar 9extending downwardly from said bracket 3. Said cap is further formedwith a squared extension 10 upon which is rigidly mounted a bevel-gearedpinion 11.

Rigidly mounted in said bracket 3 is a horizontal shaft 12. Rotatablymounted in opposing spaced relation on said shaft are a pair ofbevel-gear elements 13 and 14, respectively, (see Fig. 4) in continuousmesh upon opposite sides of said bevel-pinion. Each of said bevel-gearsis formed integrally or otherwise rigidly provided with a segmental wing15 formed at one end with an arcuate slot 16 adjacent itscircumferential edge. In the same relative position at its other lowerend each wing is provided with a cam-block 17 protruding from the planesurface 15 toward the similar surface of the respective opposing Wing.Said carnblock of each said wing comprises a concave inclined face 17increasing in height toward said lower end of the respective wing. Ashas been stated, said bevel-gears are in continuous mesh upon oppositesides of the bevel-pinion 11 with the result that they oscillate inopposite directions upon the turning of the gate and resultantoscillation of the bevel-pinion; and conversely, said gate is actuatedthrough the alternate operative connection of the respective wings ofsaid bevel-gears with actuating devices which will now be described.Loosely pivoted at one end to said shaft 12 is a lever 18 pivotallyconnected at its opposite end to a link 19 whose upper end is in turnpivotally connected at one extremity of a power-lever 20 which isfulcrumed intermediate its ends, as at 21, in said post 1 and providedwith a weight 22 adapted to be adjustably positioned. along the lengthof the lever. Numerals 23 and 2% represent cords severally attached tosaid weight or power-lever and running through a block 25 secured to thetop of said post, extend respectively in diverse directions and arrangedwith their opposite ends, not shown, within convenient reach of thewayfarcrs on horseback or in vehicles and at a distance from the gate. Avibratile bolt 26 (see Fig. 5) is housed in a chambered extension 27formed upon said lever 18. Said bolt is substantially triangular inconfiguration and pivotally mounted at 28 centrally of the extensionchamber and having its bolt ends 29 and 29 respectively protruding fromthe opposite open ends of said chamber, and positioned relative to thecommon axis 12 of said wings and lever 18 to engage in said slots 16 andbe effected by said cam-blocks 17. Said bolt is thus arranged to bevibrated from one side to the other upon the pivotal pin at 28 and isformed with-abutments 30 upon each of said bolt-ends to engage with therespec tive wall and limit the amount of projection of the opposite boltend.

To open or close a swinging gate to its fullest extent requires amovement on its pivotal supports of approximately ninety degrees orone-quarter of a circle. Such movement is effected through thebevel-pinion by actuation of one or the other of said bevel-gearsthrough operative connection of their respective wings 15 with saidlever 18 through the bolt 26. hen said gate is in its normal open orshut condition, said wings are positioned respectively at the twoopposite extremities of their travel, as shown in full lines in Fig. 1and in full and broken lines in Fig. 3. Said bolt is engaged with theone of said wings which is at the bottom of its travel and in raisingthe same to open or close the gate through its geared connection withthe bevel-pinion 11 co-incidentally effects the lowering of the oppositewing which may be similarly engaged upon the following upward movementof the lever 18 to effect the opposite movement of the gate.

The respective wings are vibrated in opposite vertical directions ateach complete swinging movement of the gate and are al ternatelyactuated during their upward movement while the opposite wing isdescending to the lowermost relative position to be engaged upon thenext upward movement of the lever 18.

As shown and described the gate is opened or closed through the powerexerted by the weight 22 in descending from its uppermost position,indicated by dotted lines in Fig. 1, to that illustrated in full linesin the view. With the apparatus in the latter position, the bolt 25 hasits bolt-end 29 or 29 in the slot 16 of the wing which is uppermost.VJith a pull exerted upon lines 23 or 2 1, the inner end of saidpower-lever 20, the link 19 and the lever 18 are lowered. Such downwardmovement of the lever 18 relative to the uppermost wing causes therespective inclined edge 26 of the bolt 26 to engage the wall of saidslot 16 and effect the retraction from the latter of the boltendengaged, say 29 to a medial position between the two wings illustratedin Fig. 2. Further downward movement of the lever 18 brings saidbolt-end 29 into engagement with the cam-face 1'? of the uppermost wingwhich influences the bolt laterally into the oppositely positioned slot16 of the low ermost wing. Then when the pull exerted upon said lines 23or 21 is released, the weight begins to descend raising the lever 18 inits progress. The bolt-end 29 entered within said slot 16 raises therespective wing which actuates the gate to open or close the same and atthe same time causes the oppo site wing to descend to where it may beengaged upon the next descending movement of lever 18.

The gate is provided with a latch that may be released before the openor closing movements of the gate are begun. Such latch and releasingmechanism therefor may be described as follows: The long arm 31 i of thelatch-bar is receivable in a notch of a braclre 32 upon an abuttinggate-post 33 and also upon a post (not shown) at the termination of thegates opening movements. Said latch-bar is pivoted at 3 1 and the shortarm thereof upon the opposite side of said pivot is engaged by the armof a bell-crank 35 whose other arm is connected with one end of a rod 36whose opposite end is connected in similar fashion to a bellcrank 37.

38 indicates a releasing bar slidably mounted upon the gate and providedwith a notch 39, and connected with the link 19 by a rigid rod 1-0. Whenthe weight 22 is elevated to actuate the gate the link 19 is forceddownwardly coincidentally with the lever 18, the rod 40 forcingdownwardly the bar 38 until the lateral arm 37 of the bell-crank 37 isengaged in notch 39. Upon the first upward operative movement of thelink 19 and lever 18 the releasing bar is influenced upwardly tooscillate said bellcrank 37 and the connected bell-crank 35 to releasesaid latch-arm 31. In the upward movement of l ver 18 there is provideda small amount of lost motion before the movement is communicated to therespective wing 15. This may be accomplished by pro portioning thelength of the slot 16 relative to the respective end of the bolt 26 toallow of some movement of the latter before the wing is influenced.

It will be understood that the lines 23 and 2 1- are led to a suitabledistance upon each side of the gate, respectively, to be grasped by thetraveler in a vehicle before reaching the gate. He pulls upon the lineto elevate the weight 22 whereupon the falling weight directly actuatesthe opening of the ate. Upon passing through the gate the passengersimilarly employs the other line to raise the weight 22 to close thegate after him.

The invention is simple in construction, is positive and reliable inoperation, and is extremely well-adapted for the purposes for whichintended.
